Abstract: Two years research experiment was conducted during Kharif season of 2015 and 2016 to investigate the, “Agronomic assessment of different rice hybrids for sustainable production through agronomic manipulation under high rainfall conditions of Konkan†at Agronomy Farm, College of Agriculture, Dapoli, Dist. Ratnagiri (M.S.). The field experiment was laid out in split-split plot design comprising 48 treatment combinations replicated thrice. Main plot treatment consisted of four sowing times viz., 23rd metrological week (4th to 10th June) (S1), 25th metrological week (18th to 24th June) (S2), 27th metrological week (2nd to 8th July) (S3) and 29th metrological week (16th to 22th July) (S4). The sub plot treatment consisted of four rice hybrids i.e. Sahyadri (H1), Sahyadri 3 (H2), Suruchi 5401 (H3) and PA 6444 (H4) while, sub-sub plot treatment comprised of three age of seedling, viz., 15 days after sowing (A1), 30 days after sowing (A2) and 45 days after sowing (A3).
The growth characters of rice viz., mean plant height, number of functional leaves hill-1, number of tillers hill-1, dry matter accumulation hill-1 yield attributes and yields were significantly enhanced due to sowing during 23rd meteorological week over 25th, 27th and 29th meteorological week in that descending order of significance. Significantly more growth, yield attributes and yield of rice was recorded in the hybrid Sahyadri 3 (H2) which were at par with hybrid PA 6444 (H4) and recorded significantly superior growth parameter over rest of hybrids at all stages of crop growth during both the years of investigation and transplanted with 15 days old seedling recorded more growth and yield during both years of study.
